To all ,whom it `may concerti."

Be it known that ALBERT J.`Lnw1s, a citi-V tlers for lVindows, of rwhich the following is a specification.

The present invention relates to antirattler for windows of dwellings and vehicles and is primarily designed to produce a de vice which will be automatic in its nature.

One of the principal features resides in a construction which may be formed from a single strip of wire andV which at the same time includesA an attaching means for the device.

Another feature resides in a construction, the tension of the anti-friction 4roller of which on the window sash may be readily varied. Y

Other features residein the extreme simplicity of the arrangementland in the particular construction and operation of the device.

In the accompanying drawings,

Figure 1 is a front view of a. window showing the application of my anti-rattler thereto.

Figure 2 is a side elevation of the antirattler complete,

Figure 3 is an end elevation of the Vdevice shown in Figure 2 and at right angles there'A to, and

Figure 4 is an enlarged fragmentary view of a window, showing the device as applied and Figure 5 is a side view of the device modilied as to its attaching means.

Referring now more particularly to the drawings by numerals of reference, 2 indi cates the frame of a window, 4 and 6 respectively the upper and lower slidable window sash and 8 the usual guide-stops therefor, and while theanti-rattler. hereinafterY described is especially useful inV connection with the windows of dwellings, it may be applied to the windows of vehicles with equal advantages. Y

The anti-rattler comprises a spring wire strip 10, bent intermediate its endsV to form a multiple coil tortion spring 11, the axis of which is arranged at'right angles to the axis of the oppositely disposed arms 'l2 and Sauany aghi angles a prev-ieee laterally extending prong; 16, the aast-'f what-ris;

substantially parallel with that of thea-Xie of the coil spring 11, said prong being' adapted to be driven into theside of the guide stop 8.V i

The outer end of the arms 14, is also bent similarly toi the prong 16 to provide a bearing spindle 18 for an anti-.friction roller 20, adapted to be yieldingly held infengagement with the window sash throughA the tension of the coil spring 11.

The coil 11 is adapted to receive a pinor i nail 22, whichpasses axially therethrough, andrinto the lsash guide 8, said pin serv@ ing as the pivot or fulcrum upon which the roller supporting arm swings. Y

As shown in Figure 2, the arms 12 and 14 are arranged at an angle of substantially 45 degrees so that the roller, 20, will be offset inwardly from the vertical plane of the upper arm 12, and will engage the window sash with the proper degree, of pressure. This degree of pressure may of course be varied by changing the angular'relation of the arms 12 and 14.

If preferred in. lieu of the attaching' prongA 16, I may form the end of the arm 12 into an eye, the aXis of which will lie ina plane parallel with that of the axis of the coil spring.v Further, it isto be understood that the anti-rattler will necessarily be made both rightand left hand for attachment to opposite sides of the'window. v l

From the foregoing description of the construction of my improved apparatus, ity

will Vloe Seen that I have provided a simple, lnexpenslve and efficient means for carrying out the objects of the invention, and while I have particularly described the elements best adapted to perform the functions set Y l Y.

forth, it is obvious that various changes in form, proportion and in the minor de-l tails of construction maybe resorted to without departing fromthe ,spirit or sacri- {icing any of the principles ofthe invention.

What I claim as new and desire'to protect by Letters Patent is:

` In combination with a window frame, a

vertically lslidable sash therein, and a guide .strip forsaid sash; an anti-rattling device for the sash comprising a single strand of resil-lr ient wire convoluted lintermediate its ends to form a coil, the wire continuing from the' terminal coils .of said convolutions being extended to form a pair of oppostely projected arms, the ends of said arms being bent at right angles in the same direction9 one of sald angular bent ends berng tapered to form an engaging point adaptedy for intro! duction in the out-er side face of guide strip, a pin having an enlarged' head at one end thereof extended through seid convolutions and engaged With the outer :tace of said guide strip in a vertical plane forward of the vertical plane of the engagementVv of the aforesaid bent end Yof the one arm, seid pin servng'as a ulorurn point'for' the oonvoluted portion 'of the VWire and the heed thereof serving to prevent the convolntons from being distorted laterally, and a roller journaled on the angular bent end ol "the opposite erm of the Wire disposed. in frietionzl] Contact W-lth the front fase of the n frame of the slidable sash, as and for the 20 purposes described.
